Research On Risk Control Of Test Oil For High Gas Oil Wells

Currently, the high gas oil wells are broadly exploited both domestically and abroad .However high gas well belongs to special well condition.The risk factors include high pressure, corrosion, etc which are likely to cause high-pressure pipeline and three-phase separation equipment leak, causing fire and explosion, then causing casualties and property losses.Based on the collection of relevant information and data,the main risks of the high gas wells are fire and explosion of the horizontal three-phase separation equipment and high-pressure pipeline.Based on PGD modle and MGD modle which are from accident simulation software CIRRUS,taking specific characteristics of parameters into consideration such as media components and phase state in three-phase separation equipment and high-pressure pipeline,flash fire and pool fire modle of horizontal three-phase separator and high-pressure pipeline were established by DANGERS Simulator .The numerical simulations of jet fire was conducted ,then flame geometric dimensions ,flame temperature properties and behavior of thermal radiation were analyzed. Calculation of risk analysis and impact prediction models were used to predict death radius, serious injury radius, minor injuries and property damage radius causing by the accident. And predict the destruction of the surrounding environment under the circumstance of toxic leak in the steady state.At last, the method is applied to the risk evaluation of high gas oil wells, and proved to be effective.It also provides the necessary theoretical basis and data support for high gas wells to ensure them safely and efficiently carried out.
