Abstract
The invention relates to the technical field of oil production engineering and belongs to a ground-driven underground horizontal boring method for an oil well. The invention aims to solve the problem that the prior horizontal drilling equipment can not drill deep holes during the conduction. The invention is mainly achieved through the following steps: driving an underground sucker rod 3 to rotate by using a rotating motor on a ground system 1; driving a flexible shaft 4 and a drill head 9 to rotate and feed through the sucker rod 3; firstly boring on the wall of a sleeve; then carrying the flexible shaft 4 and the drill head 9 to feed by using the sucker rod 3; and continuously boring on a cement sheath and a storage layer. The invention has the advantages of simple structure and convenient control and can be used for horizontally boring the deep holes underground.
Description
Technical field:
The present invention relates to the oil field technical field of oil production engineering, belong to a kind of ground-driven underground horizontal boring method for oil well
Background technology:
At present, waterpower deep penetration jet perforating technology is a kind of raising the output reforming technology of field use, but waterpower deep penetration jet perforation is because this process equipment complex structure; The well head operation pressure is high, and is harsh to water quality requirement, and winter can't construction operation; In work progress, also need pump truck, tank car, cost is also than higher, and the compaction band that forms in the near wellbore zone; Greatly reduce the flow conductivity of oil-water well near wellbore zone, and oil-water well oil layer positioning deep penetration horizontal drilling device is being researched and developed, it can only be accomplished and bore the dark hole of 1.5m of passing through the contaminated zone, near wellbore zone; Can't drilling deep hole, reduced the range of application of oil-water well oil layer positioning deep penetration horizontal drilling.
Summary of the invention:
In order to solve the problem that existing horizontal drilling equipment can't drilling deep hole in work progress and invent a kind of ground-driven underground horizontal boring method for oil well.
Technical scheme of the present invention is through realizing with lower device: ground system, centralizer, sucker rod, flexible axle, oil pipe, flexible shaft protecting, connector, brill gun main body, drill bit and supporting slip; Wherein the ground system lower end is connected with the sucker rod upper end of carrying centralizer; The sucker rod lower end is connected with the flexible axle upper end; The flexible axle lower end is connected with drill bit, and the lower end of connector is threaded with the upper end of boring gun main body, bores the gun main body lower end and is connected with the supporting slip upper end; In the inner chamber after flexible shaft protecting is inserted connector and the brill gun main body is connected, flexible shaft protecting, connector, brill gun main body and supporting slip have been formed the down-hole horizontal boring tubular column structure; Said method is realized through following steps:
A. at first connector, brill gun main body are connected with supporting slip successively; And flexible shaft protecting inserted connector and bores gun main body the inner chamber after being connected; Form the down-hole horizontal boring tubular column structure, and utilize oil pipe that it is arrived the target zone position down, carry out grappling through supporting slip then;
Sucker rod, flexible axle and the drill bit that b. will carry centralizer are connected the assigned address in the running string of back;
C. drive down-hole sucker rod rotation by the electric rotating machine on the ground system, drive flexible axle and drill bit is rotated and feeding through sucker rod, perforate on casing wall earlier, then sucker rod carries flexible axle and drill bit feeding, and continuation is holed on cement sheath and reservoir;
D. after the sucker rod that carries flexible axle and drill bit feeding is covered stroke, continue rotary flexible shaft, carry sucker rod on ground on slowly simultaneously, regain drill bit, accomplish boring.
Compared with present technology the present invention has the following advantages: owing to take said method; Can in sleeve pipe, cement sheath and reservoir, get out the lateral aperture that eyelet is dark, the aperture is big; And solved the problem that oil-water well oil layer positioning deep penetration horizontal drilling device can't drilling deep hole; Have simple in structurely, control is convenient, has improved the advantages such as range of application of horizontal drilling.
