Background technology
Jetting process pipe string is the conventional process tubing string of oil field compression fracture perforation continuous cropping construction operation, and its feature is that perforation and pressure break are effectively combined in a process pipe string, saves perforation working procedure one.But, straight well and perforating and fracturing number of plies of horizontal well increase at present, the exploitation of multilayer layering fixed tubular column Water jet packing tool has been subject to the restriction of borehole size and has been difficult to realize, and packer repeatedly sets easy inefficacy for a long time in high temperature and high pressure environment, so develop this kind of Water jet packing process pipe string in multilayer hydraulic jetting fracturing, by dragging the mode of tubing string, can effectively protect the Water jet packing tool of construction layer not and can guarantee, under construction quality and safe prerequisite, the performance of Water jet packing tool packing element and nozzle is performed to maximum.
Summary of the invention
The object of the present invention is to provide a kind of using method of Water jet packing tool, existing because being subject to the restriction of borehole size to be difficult to realize to overcome existing Water jet packing process pipe string, and packer repeatedly sets the problem of easy inefficacy for a long time in high temperature and high pressure environment.
For reaching above-mentioned purpose, the invention provides a kind of Water jet packing tool, its special character is, by the Water jet packing tool of different size, according to reservation, is linked in sequence and forms.
A kind of Water jet packing tool, its using method comprises the following steps:
1), by the process pipe string being linked in sequence according to reservation by the Water jet packing tool of different progression, be lowered to predetermined depth location;
2) steel ball of corresponding size is dropped into this process pipe string from well head; (when horizontal segment, need to use the pumping of pump small displacement);
3) steel ball can, by the internal diameter hydrajet tool larger than its outside dimension, be seated on the sliding sleeve of hydrajet tool of corresponding size;
4) well head continues small displacement pumping liquid;
5) oil pressure is increased to while being greater than opening pressure, and the hydrajet tool of this corresponding size is unlocked and first floor construction layer is constructed;
6) the rear termination of pumping of having constructed, upwards drags tubing string by well head, will in the hydrajet tool of this corresponding size, mention second layer construction layer predeterminated position;
8) well head continues small displacement pumping liquid;
9) oil pressure is increased to while being greater than opening pressure, the hydrajet tool of this corresponding size is unlocked and second layer construction layer is constructed;
10) the rear termination of pumping of having constructed, upwards drags tubing string by well head, just in the hydrajet tool of this corresponding size, mentions tri-level construction layer predeterminated position;
12) well head continues small displacement pumping liquid;
13) oil pressure is increased to while being greater than opening pressure, and the hydrajet tool of this corresponding size is unlocked and tri-level construction layer is constructed;
14) hydrajet tool of this corresponding size is completed after the construction of tri-level construction layer, in well head, throw another steel ball, by opening with the corresponding hydrajet tool of this another ball size in described process pipe string, carry out equally above-mentioned construction, so repeatedly, until whole construction layer constructed.
Step 2) in when the steel ball of corresponding size is dropped into from well head to described process pipe string, if need with this steel ball of pump small displacement pumping at the horizontal segment of oil pipe.
According to how many decisions of the construction number of plies, be lowered to how many grades of hydrajet tool, the 3 × construction number of plies=1 × be lowered to progression.
Advantage of the present invention is: the Water jet packing tool of different size is synthesized to a process pipe string according to certain der group, by pitching skid cover mode open corresponding Water jet packing tool, mode by upper lifting pipe post is constructed to different construction layers position successively, simple in structure, easy to operate, be not subject to the restriction of borehole size, avoided packer in high temperature and high pressure environment, repeatedly to set for a long time the phenomenon of easy inefficacy, there is good compliance and longer application life.

The specific embodiment
Be illustrated in figure 1 the structural representation of the Water jet packing tool that the present embodiment provides, be not difficult to find out, this multi-stage water power sprays packing process pipe string and is linked in sequence and forms according to reservation by the Water jet packing tool of different size, it is three grades of Water jet packing process pipe strings that multi-stage water power shown in this figure sprays packing process pipe string, mainly the guide shoe 4 that is arranged on one-level Water jet packing tool 1 outside oil pipe 5, secondary Water jet packing tool 2, three grades of Water jet packing tools 3 from bottom to top and is arranged on the bottom of oil pipe 5, consists of; Certainly, in this figure, giving construction layer is first floor construction layer 6, second layer construction layer 7, tri-level construction layer 8 ... N construction layer 9 and well head 10.
On the basis of Fig. 1, we are in conjunction with Fig. 2,3,4 and 5, and the work progress that the multi-stage water power injection packing process pipe string that the present embodiment is provided will carry out is that method is described in detail:
The using method of the Water jet packing tool providing by the present embodiment, the process pipe string being linked in sequence of first Water jet packing tool by different progression being opened according to pitching, is lowered to predetermined depth location; Then the steel ball 11 of (Ф 34-Ф 47) is dropped into this process pipe string from well head 10; (when horizontal segment, need to use pump little Pai Liang≤0.5m
3/ min pumping); Steel ball 11 can, by the internal diameter hydrajet tool larger than its outside dimension, be seated on the sliding sleeve of one-level Water jet packing tool 1; Well head continues small displacement pumping liquid; Oil pressure is increased to while being greater than opening pressure, and one-level hydrajet tool 1 is unlocked and to first floor construction layer 6 (see figure 2) of constructing; The rear termination of pumping of having constructed, upwards drags tubing string by well head, will in one-level hydrajet tool 1, mention second layer construction layer 7 predeterminated positions; Well head is by operational discharge capacity pumping liquid and to second layer construction layer 7 construct (shown in Fig. 3); The rear termination of pumping of having constructed, upwards drags tubing string by well head, will in one-level hydrajet tool 1, mention tri-level construction layer 8 predeterminated position; Well head is by operational discharge capacity pumping liquid and to tri-level construction layer 8 construct (shown in Fig. 4); One-level hydrajet tool 1 is completed after the construction of tri-level construction layer, in well head, throw another steel ball 12, by in process pipe string with this another steel ball 12(Ф 39-Ф 47), secondary hydrajet tool 2 is opened to (see figure 5), carry out equally above-mentioned construction, so repeatedly, until whole construction layer complete.
The concrete progression that the multi-stage water power that the present embodiment provides sprays packing process pipe string determines according to the construction number of plies.3 × construction the number of plies=1 × be lowered to progression.
