Research On Key Techniques Of Three Dimensional Horizontal Wells In Surig Gas Field

Changqing oilfield in the large-scale deployment of horizontal well this year, well spacing significantly increased number of cases, combined with the regional development features, well spacing and horizontal well development process, design implementation factory level well group. The factory construction in changqing oil field is a key development project, Throght this mode, the operation speed up and shorten the production cycle, meets the requirements of low cost development, formed the factory with the characteristic of the zone drilling and completion operation mode, helping achieving the commercial and cost-effective development of such this gas fields with low pressure, low permeability and low abundance.and factory construction is bound to play 3 d horizontal well. In this article, through 3 d horizontal well discusses some problems that should be paid attention to in the construction, In order to achieve the purpose of preventing collision avoidance, the optimization design of the well profile, wellbore trajectory control and drilling fluid performance maintenance and other key technical measures are well designed. Achieve the goal of safety rapid construction 3-d horizontal well.
