Northwest Oilfield gas lift valve effect is significant

This year, Northwest Oilfield Engineering Technology (Valve Technology) Research Institute of the Tahe heavy oil well gas injection through the high-pressure gas lift valve successfully achieved multiple wells gas injection and normal production, save a total cost savings of 15 million yuan workover , Resulting in economic benefits 12 million yuan. Oil well gas injection requires the use of high pressure gas sealing pipe supporting gas seal packer to prevent gas leakage occurred in the process of column leakage and other safety accidents. At present, most of the heavy oil injection in Tahe Oilfield is made of rare-earth gas injection valve, which is non-hermetically sealed valve. It is difficult to close after opening, which makes it difficult to meet the requirements of multiple well gas injection and high-pressure gas sealing of the oil well, Dilute production. In response to this problem, the Institute of Oil and Gas researchers through extensive research, established in the gas pipe column supporting high-pressure gas lift valve concept. The technician improved the structure of the conventional gas lift valve to a high pressure gas seal structure to achieve a gas seal pressure of 70 MPa and satisfy the gas injection requirements while improving the screw thread connection to a gas seal special seal to achieve a gas seal of the tool string To improve the opening and closing pressure of the gas lift valve, ensure that the gas lift valve is in the closed state when the gas is injected and the automatic open state during production, so as to realize the function of sparse mixing after gas injection. High pressure gas lift valve has three major innovations, one is through the improvement and improvement of conventional gas lift valve structure to meet the high pressure gas injection and sparse production requirements; the second is to lift the valve lift the valve hole size from 3.2 mm to 8 mm , To achieve a thick oil injection wells do not move the production of thin-tube mixed production; third is through two-valve lift valve design to reduce the risk of valve plugging to improve the flow area. The improved gas lift valve is applied to heavy oil gas injection wells for on-the-spot testing. During the gas injection process, it is not necessary to conduct the workover pipe string operation. After the gas injection, the valve hole of the gas lift valve is sparsely produced from the annular space, High pressure gas injection and dilution production requirements for heavy oil wells. Up to now, a total of 15 heavy oil wells in Tahe Oilfield have applied high-pressure gas lift valve to gas injection, successfully achieving gas injection and sparse mixing production.

Double J Hooks

We are putting most of our resource and effort into Ratchet Straps and their accessories.

Besides ratchet buckle,straps,what else is missing?

Yes,End Fittings,so here are what we strongly suggest-double J Hooks.

This could be the most popular end fitting for ratchet straps,almost all the ratchet straps are using this-for its universal ability to hook at any holes,anchors.

And yet,you can only get hooks here or the whole ratchet straps with hooks,galvanized or black coated or even stainless steel,all up to you!
