Abstract

Destabilizacija konsolidiranih i nekonsolidiranih ležišta uvelike pridonosi smanjenju proizvodnje ugljikovodika i uništenju proizvodne opreme. Veliki uzrok tome je i kolaps perforacije koja uzrokuje proizvodnju pijesaka. Stabilnost bušotine i perforacija ovise o prethodnim operacijama, gustoći perforacijama, njihovom usmijerenju i kritičnoj udaljenosti između perforacija. Povezivajući vrijednosti dinamičkog tlaka na dnu, pada tlaka u bušotini i u perforacijama, usmijerenja perforacija, čvrstoće stijene i naprezanja unutar nje, može se izbjeći proizvodnja pijesaka.

Abstract (english)

Abstract: Destabilization of completed sandstone reservoirs reduces production rates and degrades production equpment. A major cause of such destabilization is perforation failure which couses sand production. Stability of the wellbore and perforation tunnel strongly depends upon drilling and perforation directions, perforation shot density and the critical distance between perforations. The relationships of the bottomhole flowing pressure, drawdown, perforation orientation, rock strenght and in- situ stresses are given to provide optimal perforation for mitigating sand production.
