Horizontal Blasting Parameters Research And Application

Along with the application of horizontal well technology in Liaohe Oilfield,the crude oil recovery was improved.However,because of some body structure factors of horizontal wells,such as the kick off section and horizontal section too long, the irregular change of shaft axis and so on, which cause the difference of conventional workover operations technology between horizontal wells and ordinary oil wells.Especially in the sand washing construction, for the complexity of heavy oil horizontal wells, sticking of drill tools accident is easier to occur, and causes great economic losses.This paper is based on the brief introduction of the main methods and technology in the field of sa-nd washing,and it applies theory model to research on the basic parameter of horizontal well and the features of heavy oil horizontal well in the Huanxiling heavy oil block of Liaohe Oilfield. Through the research and analysis of oil viscosity and loss situation of heavy oil block horizontal well in the Hua-nxiling, we can get effective viscosity and plugging technology of heavy oil horizontal well in heav-y oil block. Combination of horizontal string matching parameters and strength parameters, the mini-mum displacement field of horizontal blasting parameter table, the viscosity of horizontal Wells and proposed glad ridge plugging technology heavy blocks blasting technology and horizontal supporting tool for horizontal blasting block mian provide reasonable suggestions.Because in horizontal Wells at home and abroad blasting operations research less commonly. Ther-e are important significances in mastering of flow encapsulation of horizontal rule,making sure the bl-asting parameters and mode, correctly matching blasting equipment and facilities, increasing oil pro-duction and so on. So it is especially important that rejoice in liaohe oilfield ridge area blasting param-eters of heavy oil horizontal wells and blasting technology application.
