Abstract
The utility model relates to an electric pump cable lateral wing crossing and sealing device. The device consists of a connecting flange, a crossing body, a combined seal, a main seal, a secondary seal, a large gland, a small gland, an electric pump cable and a supporting ring. The device has the characteristics that: the electric pump cable passes through an original tubing head side opening; the device has a simple structure; the cable is not damaged due to single-phase cable sealing; and the overall sealing property of the seal of the electric pump cable and the tubing head is guaranteed through double-channel sealing property detection. The crossing mode and the sealing structure of a wellhead cable are changed; and the problems such as a complex structure, easiness in squeezing damage of the electric pump cable and unavailable detection of the sealing property in the conventional device are solved.
Description
Technical field
The utility model relates to a kind of electric pump cable flank and passes through sealing device, particularly electric pump well head cable sealing device.
Background technology
At present, both at home and abroad the petroleum industry electric pump is produced employed traditional well head cable and is passed through sealing and all adopt electric pump cable well head upwards to pass through, seal.Structure is the hole of passing through that has the electric pump cable on the end flange of the oil recovery four-way that is connected with the tubing head upper vertical, pass through the hole and be provided with seal chamber, cable passes three hole rubber seal in the seal chamber, three mesoporous metal packing rings are tightened together by the end flange of connecting bolt, nut and oil recovery four-way.The hole of passing through that has the electric pump cable on the end flange of oil recovery four-way makes shaft collar complicated more; because hermetically-sealed construction is single, can't pressure testing; for reaching sealing performance, it is excessive to exert pressure to seal combination, causes the protection crust of electric pump cable to be subjected to excessive compression and damages; cable bad; tubing head top is the production of hydrocarbons passage, and cable is dipped in the oil gas, and electric current passes through during production; cable breakdown causes losses such as changing cable, stopping production.
Summary of the invention
The purpose of this utility model is easily squeeze to hinder and sealing performance such as can't check at problem at existing structure complexity, electric pump cable, provide a kind of novel electric pump cable flank to pass through sealing device, this device by adpting flange, pass through body, combination sealing, primary seal, secondary sealing, big gland, little gland, electric pump cable, support ring is formed; Pass through body, support ring, combination sealing, packing ring and little gland and form the seal assembly that passes through of electric pump cable, secondary pressure testing hole is the pressure testing passage of checking cable seal performance; Pass through seal assembly and place adpting flange to be connected with primary seal, secondary sealing, big gland, bolt combination, the pressure testing passage of the overall sealing performance of sealing device is passed through for checking electric pump cable flank in main pressure testing hole.This apparatus features is that the electric pump cable utilizes former tubing head side opening to pass, and is simple in structure, single-phase cable seal, and cable preserves from, and the double sealing Performance Detection has guaranteed the overall sealing performance of electric pump Seal of Cables and tubing head.Changed mode and hermetically-sealed construction that the well head cable passes through, solved that existing structure complexity, electric pump cable easily squeeze to be hindered and sealing performance such as can't check at problem.
A kind of electric pump cable flank described in the utility model passes through sealing device, be by adpting flange, pass through body, combination sealing, primary seal, secondary sealing, big gland, little gland, the electric pump cable, support ring is formed, fixedly primary seal (12) and the secondary sealing (10) respectively at the two ends of passing through body (2), the middle part of passing through body (2) is provided with secondary pressure testing hole (4), pass through in body (2) inner chamber and be fixed with support ring (11), fixed combination sealing (9) respectively on the end face at support ring (11) two ends, the little gland (7) at support ring (11) two ends by screw thread with pass through body (2) and be connected, between combination sealing (9) and the little gland (7) packing ring (8) is set.
Pass through and be provided with the cavity that 3 electric pump cables (13) that are triangularly arranged pass through in the body (2), cavity is communicated with pressure testing passage (17).
Pass through body (2) and insert in adpting flange (1) inner chamber, adpting flange (1) is provided with main pressure testing hole (3), and big gland (5) is connected with adpting flange (1) by bolt (6).
