Abstract
The utility model relates to a sewage return injection device for the development of the oil field of beach sea and land remote areas. The device is composed of a hanging body (7) in an opposite-open type, the upper pressing cap (4) of the hanging body, a return injection pipeline (1) of high pressure, a check valve (2), a stop valve (8), joints (3), (6), a sealing rubber ring (5) and a pressure meter (9). The device has simple structure and reliable work. Adopting the utility model can conveniently and rapidly realize the sewage return injection of the well of the beach sea and land remote areas, reduce the environment pollution and reduce the treatment cost.
Description
The utility model relates to a kind of soiling solution re-injection device that is used for sea, beach and the oil field development of outlying district, land.
Must produce a large amount of soiling solutions in the oilfield development process, comprise sump oil, sewage, discard into well working fluid etc.The oil field, land takes methods such as sump oil recycling, sewage clarification re-injection, discarded slurry processing recovery to be handled usually, and the face of land that a part is then abandoned disappears by evaporation, weathering.In carrying out above-mentioned processing procedure, need to be equipped with a large amount of separation of use, purification, re-injection, reclaimer and expense input.Yet for the outlying well in land or sea, beach and offshore field, the soiling solution intractability is bigger, becomes the important topic that domestic and international oil field development fails to obtain fine solution for a long time.At present, the outlying well in land is usually by the discharging of digging pit, and the not far beach Hai Jing of offshore then transports soiling solution back land by cargo ship and handles.Like this, not only investment is high, and workload is big, and is difficult to reach environmental requirement.The U.S. had once designed a kind of device with waste materials such as oil-contained drilling cuttings, waste mud injection offshore field annular space, but this apparatus structure complexity is applicable to the area, deep-sea, is not suitable for the Tan Hai oil field and uses.
The purpose of this utility model is to provide a kind of oil field development soiling solution re-injection device, utilize this device can Jiang Tanhai and the soiling solution that in drilling well, oil recovery, operation process, produces of outlying district, land oil well be recycled into deep formation, thereby the reduction processing cost reduces the pollution of soiling solution to land, marine environment.
The utility model is to realize like this, this device is made up of high pressure re-injection pipeline, ball-and-seat, joint, suspension body upper pressing cap, O-ring seal, opposite opened suspension body, stop valve and pressure meter, its structure and assembling feature are as follows: suspension body upper pressing cap both sides are connected to joint by screw thread respectively, the joint of one side connects ball-and-seat by screw thread, ball-and-seat connects high at the re-injection pipeline again, the joint of opposite side connects stop valve by screw thread, and stop valve connects pressure meter again; The suspension body upper pressing cap is sleeved on outside the oil well inner layer sleeve box cupling, its periphery is connected with the outer layer sleeve box cupling by screw thread, suspension body upper pressing cap below is provided with the opposite opened suspension body, and suspension body is sleeved on outside the inner layer sleeve, and its periphery is placed on the outer layer sleeve by the step seat; Between suspension body upper pressing cap lower taper inclined-plane and the inner layer sleeve box cupling O-ring seal is housed.This device erection procedure is as follows: after intact inner layer sleeve and cementing operation under the drilled well, the opposite opened suspension body is put into the outer layer sleeve box cupling; Transfer inner layer sleeve, make inner layer sleeve box cupling seat on suspension body, lay down the landing joint on the inner layer sleeve box cupling, put into O-ring seal; The suspension body upper pressing cap is sleeved on outside the inner layer sleeve box cupling, and the connecting thread that screws between pressure cap and the outer layer sleeve compresses O-ring seal; Be connected to ball-and-seat, high pressure re-injection pipeline in turn suspension body upper pressing cap one side by joint, stop valve, pressure meter are connect the pressure cap opposite side successively by joint.When this re-injection device used, soiling solution was pressed into the stratum by the annular space between outer layer sleeve and the inner layer sleeve again at the effect lower edge of infusion pump high pressure re-injection pipeline, ball-and-seat, joint, suspension body upper pressing cap re-injection passage, suspension body re-injection passage.
The utility model is simple in structure, and is easy to implement, and suspension sleeve need not conventional welding procedure, and reliable operation is utilized it to make things convenient for, promptly the outlying well in sea, beach or land realized the soiling solution re-injection, reduces environment pollution, reduces processing cost greatly.
Accompanying drawing is a general structure schematic diagram of the present utility model.Wherein, label " 10 ", " 11 ", " 12 ", " 13 " are respectively oil well outer layer sleeve box cupling, outer layer sleeve, inner layer sleeve box cupling and inner layer sleeve,
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, suspension body upper pressing cap 4 is a hollow cylinder, and its periphery both sides, top have relatively for jointing screw and vertical with it circular arc re-injection passage, and channel bottom 20-30mm highly is annular, connects along circumference; The bottom periphery has for the pin thread that is connected with oil well outer layer sleeve box cupling, and bottom inner headed face band tapered slope is so that compress the sealing ring of its below.Opposite opened suspension body 7 is made up of dress two hollow semicylinders of opposite opened, its top is 1: 16 taper seat of tapering, the middle and upper part periphery is provided with abutment and hangs over step on the oil well outer layer sleeve, between the inside and outside disc along circumference be provided with pressure cap on 4-8 vertical passage that runs through being docked and connected of annular re-injection passage, tapered inclined-plane, inner headed face bottom.All the other each parts such as high pressure re-injection pipeline 1, ball-and-seat 2, joint 3,6, O-ring seal 5, stop valve 8 and pressure meter 9 are conventional part.
