Description
The method and apparatus of the multi-stage cementing of well cover in the present invention relates to hole.Particularly, thus multi-stage cementing of well casing method and apparatus involved in the present invention make to go up casing string in the second stage of slip casting can and be independent of lower casing string and rotate the abundant displacement that guarantees any liquid in the boring.
In the operation of various oil minings, when boring has reached several thousand feet when dark, a steel sleeve just is placed in the well produces required geologic(al) formation or layer group to be separated out one.This sleeve pipe is bonded in there to prevent that loose geologic(al) formation from collapsing and to prevent that the liquid of different geologic(al) formations from mixing mutually.In addition, sleeve pipe is used to also prevent that the geologic(al) formation liquid from entering boring.No matter what the reason of placing steel tubes is, unless replaced by the mixture (for example cement) of the atresia of solidifying fully at the drilling cuttings liquid of cover tube outside, boring just can not suitably be kept apart.In this slip casting process, cement injection is by the casing string boring that is depressed, and then pressed from the casing string outside, thereby makes the periphery of sleeve pipe be bonded on the drill hole wall with the mud of cement injection displacement casing string outside.The slip casting work of a success should be all drilling slurries are all replaced by cement and to make cement just be frozen into a containment vessel before liquid is invaded wherein.Because boring is very dark, be one of work of difficulty the most in all oil mining work so replace all earth along the total length of well cover with cement.If can not obtain sufficient slip casting, the drilling slurry of not replaced still may the passing hole channel vertical migration.
In addition, under the long situation of casing string, be difficult to place around the sleeve pipe cement injection is disposable because the fluid density of slip casting is greater than the fluid density of drilling slurry, thereby be difficult to by sleeve pipe slip casting depress several thousand feet dark and then by pressing several thousand feet to hell.In order to overcome this limitation, two sections grouting valves have been adopted.This valve at first makes can be depressed whole casing string and press boring and arrive a centre position just being lower than this valve of cement injection.After opening valve, the runner that is lower than the slip casting of this valve in the casing string just has been closed, and slip casting is just flowed more than the valve position at this.At this moment, only need the be depressed only about half of length of sleeve pipe of slip casting compresses the top of boring until ground by the annulus that valve opening enters boring then.
Though this two sections grouting methods have been simplified the engineering that slip casting is pressed into long casing string, if do not have the rotation of casing string or move up and down, drill cuttings still can not be replaced fully.And when boring be not fully vertical or straight or its geometry is oval-shaped or during off-centre operation, situation especially like this, in the rotation of slip casting process middle sleeve post or to move up and down be to make the mud the boring to be replaced by cement in order mud eliminating to be gone out from the bottom of boring by means of the friction between well sleeve column and the mud.Thereby under the situation of one section slip casting of the superficial only need of boring, whole casing string will rotate until the whole drill cuttings along whole casing string and all be replaced.
Whole casing string rotates or moves up and down and also has been used in two sections slip casting processes.When first section slip casting was pressed into sleeve pipe and enter the bottom of boring, casing string rotated to guarantee that the whole mud in first section are all replaced., in case this first section slip casting solidified, the sleeve pipe top that is higher than the multi-stage cementing valve just can not have been rotated in second section slip casting process.This just causes can not being replaced fully of drill cuttings in cement top.
The invention provides a kind of method and apparatus of multi-stage cementing, thereby overcome the known existing defective of casing string multi-stage cementing device that is used for.According to the present invention, go up casing string during second section slip casting and can be independent of the lower casing string rotation, thereby guaranteed the displacement of whole drill cuttings.
Device among the present invention comprises that is taken over a mechanism.Whole casing string in the middle of placing, this mechanism is connected between the upper and lower casing string near the grouting valve, so that can both rotate and the top that is higher than the sleeve pipe of multi-stage cementing valve when second section or final stage slip casting can be rotated when first section slip casting.This adapter mechanism has one to go up hub sections and a following hub sections, and they are telescopic to be installed together, and makes that going up hub sections can vertically move with respect to following hub sections.In preferred embodiment, two hub sections all have engageable spline, and whole casing string is rotated, but because of last casing string moves with respect to following sleeve column, also can make its disengagement.When spline was in disengaged condition, hub sections and setting of casing freely rotated under last hub sections and last sleeve pipe can be independent of.And because spline can freely mesh, whole sleeve pipe can rotate to both direction, and the spline disengagement afterwards even can mesh again.
The present invention is except making upper and lower casing string independent rotation, and device of the present invention can place any one position along this casing string in the normal sleeve post.Like this, as long as use spline just can finish multi-stage cementing with differentiated friction joint or length.In addition, the rotation when only being used to be controlled at different phase owing to mechanism of the present invention, this mechanism can place casing string according to different feature requests.Yet in order to reduce the cost of equipment, this adapter mechanism can connect with the multi-stage cementing valve and be combined into parts.
Used aforementioned means so that thereby upper and lower casing string can independent rotation guarantee that all drill cuttings are all replaced according to method of the present invention.When making in this way, boring is in normal state, and sleeve pipe is placed in the boring, takes over mechanism and then is installed in above sleeve pipe segmenting slip casting place tight.In the time of at the bottom of slip casting is pressed into the hole by sleeve pipe, whole casing string rotates to obtain required displacement.In case after the slip casting of scheduled volume is pressed into sleeve pipe, a valve plug is filled in the well cover, and it is pressed onto sleeve bottom.Then, open the valve bullet with one and put into sleeve pipe to open two sections grouting valves that just place under the adapter mechanism.In case middle valve opening has been opened, just begin first section slip casting operation.Served as after the time enough, broken away from engagement thereby last sleeve pipe moves down the spline that makes in the adapter mechanism.So when last casing string rotated separately, second section slip casting was replaced through last sleeve pipe.After displacement is finished in second section slip casting, drop into one and close embolism, so middle valve opening just is closed.After the displacement of slip casting is finished, each embolism in casing string can be got out, make boring unimpeded.
Therefore, the invention provides a kind of apparatus and method of easy whole sleeve pipe slip casting, can guarantee that drill cuttings is replaced fully.
Other purposes of the present invention, feature and advantage are illustrated with reference to the accompanying drawings.

At first referring to Fig. 1 to Fig. 4, wherein show and embody pipe connecting device 10 of the present invention, it links to each other with the casing string 12 that string data connects.Whole casing string 12 comprises by pipe connecting device 10 interconnective casing string 14 and the lower casing strings 16 gone up.Pipe connecting device 10 comprises and is used for selectively driving torque is delivered to the device of lower casing string 16 from last casing string 14 that upper and lower casing string can be thrown off, and casing string 14 can be independent of lower casing string and rotate under the situation that keeps each casing string to link to each other.
As shown in Figures 2 and 3, following hub sections 18 telescopicallies are packed into and are gone up hub sections 20(more particularly, promptly go up liner sleeve 28).Like this, last hub sections 20 can move with respect to following hub sections 18, and therefore, last casing string 14 can move longitudinally to position shown in Fig. 3 from position shown in Fig. 2 with respect to lower casing string 12.And the 32 1 ends conduct of last bushing central shaft 26 is the supporting surface of hub sections 18 down, hub sections 20 moving down with respect to following hub sections 18 in the restriction.On the contrary, following hub sections 18 and last liner sleeve 28 comprise respectively supporting takes on 34 and 36, moves up with respect to setting of casing 12 to limit sleeve pipe 14.Therefore, vertical relative movement distance of the parts of pipe connecting device 10 is fixed, and this has prevented that under the situation of not dismantling pipe connecting device 10 last casing string 14 separates with lower casing string 12.
Referring to Fig. 1 and Fig. 4, wherein show and be used for selectively driving torque being delivered to down hub sections 18 from last hub sections 20, can be independent of the device that setting of casing 12 rotates so that go up casing string 14.In a preferred embodiment of the invention, this device comprises the mesh splines 40 on hub sections and the following hub sections.These splines 40 preferably include down a pair of spline 42 on the hub sections 18 and a pair of spline 44 on the last hub sections 20.These splines form corresponding cannelure 46, and groove 46 holds the spline of the component of pipe connecting device 10.As shown in the figure, the width of these splines is arbitrarily, as long as corresponding groove 46 critically conforms to the width of matching spline, so that the loss that rotatablely moves reduces to minimum.But in a preferred embodiment, in fact less than the width of the spline 44 of last hub sections 20, this is in order to reduce production costs to the width of spline 42.For obtaining similar results, can adopt the spline of any number, or change is along the friction engagement of each winding duct member of each section setting of casing string 12.In addition, can change the length of spline, so that before spline is thrown off, bigger vertically moving arranged.
The assembling of pipe connecting device 10 allows that going up hub sections 20 vertically moves with respect to following hub sections 18.After seal 30 and 38 is put into its holddown groove 48, will descend hub sections 18 to pack into and go up in the liner sleeve 28, so that spline 42 embedded grooves 46.At this moment, axle 26 can be put into the end of sleeve 28, and live spindle 26, make the threads engage of each parts, thereby assemble hub sections 20.At this moment, the increasing of following hub sections 18 part 50 of diameter between the support shoulder 30 of the end 32 of axle 26 and sleeve 28.Pipe connecting device can link to each other with casing string 12 for 10 this moments, to carry out the multi-stage cementing work of casing string 12.
Referring to Fig. 5 to Fig. 9, wherein show the pipe connecting device 10 that is arranged in the whole casing string 12.Figure middle sleeve post 12 is contained in the boring 52 that feeds the possible oil and gas reserves of subsurface investigation.Casing string 12 roughly extends to the end 54 of boring 52.Casing string 12 comprises many parts that link to each other that play special role in drillng operation.But only be used in combination the necessary part description of method of the present invention method of the present invention at this.Casing string 12 comprises intermediate valve 56, and it has the transverse holes 58 of open and close selectively.Valve 56 is preferably disposed near below the pipe connecting device 10.Valve 56 and pipe connecting device 10(specifically, promptly with following hub sections 18) be one.Like this, valve 56 will also significantly reduce the cost of production of this device simultaneously with hub sections 18 one rotation down.
As shown in Figure 5, comprise that the whole casing string 12 of pipe connecting device 10 and valve 56 is in a single day following in boring 52, can begin the multi-stage cementing operation.Along with the rotation of whole casing string 12, first section cement 60 moves by the inside 62 of casing string 12, and comes out from casing string 12 ends in boring 52 bottoms 54.Casing string 12 ends have underflow hole 64, can make cement injection 60 enter boring 52.Under continuous surface pressing, cement injection 60 will upwards reflux along boring 52 in the outside of casing string 12, as shown in Figure 6.Follow cement injection 60 closely, put into first embolism 60, to guarantee constant flow, it plays scraper, forces whole cement injections 60 downward along the inside 62 of casing string 12.The counter-pressure continuous action arrives float collar 68 until embolism 66 on embolism 66.Float collar 68 comprises contraction dividing plate 70, and dividing plate 70 holds embolism 66, with the liquid stream of sealing by casing string 12.Owing to can pre-determine the volume of the required cement 60 of first section slip casting, therefore when the dividing plate 70 of embolism 66 arrival float collars 68, the height of the concrete column 60 of casing string 12 outsides will arrive below the transverse holes 58 of valve 56, as shown in Figure 7 just.Like this, along with the rotation of whole casing string 12, first section cement injection 60 is forced out suitably, guarantees the suitable extrusion and the gluing of drilling mud.
Still referring to Fig. 7, second embolism is that " bomb " 72 falls into casing string 12, to open the transverse holes 58 of intermediate valve 56.The power of embolism 72 moves down the joint ring 74 of coverage hole 58, thereby makes liquid can pass through this orifice flow mistake.Under the situation that first section cement injection 60 extrudes suitably and open in hole 58, cement injection 60 can tentatively solidify before second section slip casting work of beginning at least.
After making cement injection 60 partial coagulations, move down casing string 14, so that the spline 40 of pipe connecting device 10 is thrown off.In a preferred embodiment, need vertically move casing string 14 about 18 inches, so that the matching spline 40 of pipe connecting device 10 is thrown off.But required amount of movement will depend on the length of spline 40.When spline was thrown off, last casing string 14 can be independent of lower casing string 16 and rotate and/or move back and forth.When rotation and/or moving back and forth casing string 16, second section cement injection 80 moves by the inside 62 of last casing string 16, as shown in Figure 7.
Referring to Fig. 8 and Fig. 9, downwards the time, it can flow into boring 52 by transverse holes 58 along casing string inner 62 for second section cement injection 80.Because first section cement injection 60 solidifying below valve 56, so when cement injection 80 tap holes 58, it is forced in casing string 14 outside making progress along boring 52 and refluxes, as shown in Figure 8.With first section same, second section cement injection is after 80s promptly to seal embolism 82 with the 3rd embolism arranged, embolism 82 guarantees the abundant displacement of cement.When the sealing embolism arrived valve 56, it cooperated with inner sleeve 84 and makes it downward, seals transverse holes 58 once more, as shown in Figure 9.Owing to can pre-determine the volume of needed cement injection 80, after second section slip casting is finished, the height of the concrete column that casing string is outer will extend to ground.Between this second section operational period, last casing string 14 rotates continuously and/or moves back and forth, to guarantee the abundant displacement of cement injection 80.
Therefore, method and apparatus of the present invention can carry out the multi-stage cementing work of casing string, and the while can make casing string rotate independently during second section slip casting and/or move back and forth.Though the explanation to method of the present invention only is that two sections slip casting work that are used in combination a pipe connecting device are made, and can adopt the pipe connecting device of any number to carry out multi-stage cementing work.In addition, because most of cement has been pressed in the boring outside the casing string, so the method described in this manual has been simplified the work that gets out cement from the hole thereafter effectively.Therefore, the present invention has reduced the cost of casing string slip casting work, provides good isolation for casing string simultaneously.Isolated the ground layer lineage in the prospect pit effectively.
More than detailed description only is used to be expressly understood the present invention, and without any unnecessary restriction, because the people of skilled obviously can make some remodeling under the situation of scope that does not break away from claims and essence.
